I have also started redesigning with a ~8.5:1 ratio; the math tells me its more that enough to lift 60+ lbs at ~56 in/sec with one RC, that's calculated with the fork assembly factored in too, and ~36 in/sec with a full 6 stack, and this is with two winch assemblies of course. All the tips I received are coming in really helpful, so I'm great full for that.

Friction is a thing. I calculated for our lift a total load of 120lbs, for 6 totes + RC, and that was too low. In the end I should have calculated with around 160lbs, because we were using a forklift style lifter. I think using a C-shaped chassis would change how much friction you have to account for.
